This class lets you trigger a call into Mathematica on the occurrence of a particular event.
Like all the MathXXXListener classes, it is intended to be used primarily from Mathematica, although it
can be used from Java code as well.

In response to a TextEvent, objects of this class send to Mathematica:

userFunc[theTextEvent]

userFunc is specified as a string, either a function name or an expression
(like a pure function "foo[##]&"), via the setHandler() method.

Because the TextListener interface
has only one method, textValueChanged(), you can specify the Mathematica function to be
called with this constructor, rather than having to separately call setHandler().

Constructor Detail

MathTextListener

MathTextListener

You must use this constructor when using this class in a Java program,
because you need to specify the KernelLink that will be used.

Parameters:

ml - The link to which computations will be sent when textValueChanged is called.

MathTextListener

public MathTextListener(java.lang.String func)

Because the TextListener interface
has only one method, textValueChanged(), you can specify the Mathematica function to be
called with this constructor, rather than having to separately call setHandler().
Use this constructor from Mathematica code only.

Parameters:

func - The Mathematica function to be executed in response to an TextEvent.
